Novel Elastomeric Fabrics for the Treatment of Hypertrophic Burn Scars Using Polyhexamethylene Biguanide Antimicrobial Agents

引用

Journal of Donghua University(English Edition) 2013年第5期30卷 410-415页

作者： VARAN nilufer Y KING W Martin Department of Textile Engineering Istanbul Technical University Textile Engineering Chemistry and Science North Carolina State University

In burn treatments,microorganisms on pressure garments during pressure therapy can prevent rehabilitation by causing functional,hygienic,and aesthetic difficulties. As bacterium is one of the most trouble-causing organisms,they can threaten patients causing infection during the long period of use of these *** burn pressure garments having durable antimicrobial property were developed using polyhexamethylene biguanide( PHMB)antimicrobial agent procedure on highly elastic nylon 66 /spandex fabrics in powernet,flat warp and weft knitted structures using paddry-cure method. Commercial wireless pressure sensors were used to control pressures at an acceptable medical range. Antimicrobial activity,wash durability,Fourier transform infrared spectroscopy(FTIR) and Scanning electron microscopy(SEM) analyses were conducted for the treated samples. Antimicrobial test results following AATCC 100 Test Method showed 99% reduction of bacteria for the fabric samples treated with PHMB. A small but significant decrease in antimicrobial activity was observed even after50 launderings. These treatments also yield good results to prevent odor,decrease infection by preventing and /or blocking microbial growth according to the antimicrobial mechanism and support reducing of scarring by providing a hygienic environment around the scar.

Evaluation of systemic risk factors in different optical coherence tomographic patterns of diabetic macular edema

引用

International Journal of Ophthalmology(English edition) 2018年第7期11卷 1204-1209页

作者： Durgul Acan Eyyup Karahan nilufer Kocak Suleyman Kaynak Department of Ophthalmology Yatagan Public Hospital Department of Ophthalmology Van Training and Research Hospital Department of Ophthalmology Dokuz Eylul University Faculty of Medicine

AIM： To elucidate the relationship between systemic risk factors and different patterns of diabetic macular edema（DME） determined with optical coherence tomography（OCT）. METHODS： In this cross-sectional study, DME was classified by OCT as diffuse retinal thickness（DRT）, cystoid macular edema（CME） and serous retinal detachment（SRD） and the relationship between the systemic risk factors and DME patterns was evaluated. RESULTS： Of the 57 patients with DME, 21（36.8%） had DRT, 24（42.1%） had CME and 12（21.0%） had SRD. Microor macro-albuminuria was significantly higher in the DRT pattern（61.9%） compared with the SRD（50.0%） and CME patterns（25.0%; P=0.040）. Hemoglobin A1 c（Hb A1 c） level was significantly higher and patients were younger in the DRT pattern group（P=0.034, P=0.032）. Best corrected visual acuity was the worst and central macular thickness was the thickest in the CME pattern group. CONCLUSION： Micro-or macro-albuminuria may be more frequent and Hb A1 c level may be higher in patients with DRT. These patients are also seen to be younger than patients with non-DRT.

International Journal of Ophthalmology(English edition) 2015年第6期8卷 1162-1167页

作者： Uzeyir Gunenc Taylan Ozturk Gul Arikan nilufer Kocak Department of Ophthalmology Dokuz Eylul University School of Medicine

AIMTo evaluate the long-term efficacy and safety results of viscocanalostomy and *** charts of 49 glaucoma patients who underwent viscocanalostomy or phacoviscocanalostomy surgery between February 1999 and August 2004 were reviewed retrospectively. Thirty-one eyes of 21 glaucoma patients who underwent filtering procedure with a postoperative follow-up of at least 5y were included in the study. Results of complete ophthalmologic examinations were recorded and statistically analyzed. Long-term surgical outcome was defined as an overall success when intraocular pressure (IOP) was found as ≤20 mm Hg with or without antiglaucomatous medication at the last follow-up visit, while it was defined as a complete success when IOP was measured ≤20 mm Hg without antiglaucomatous *** age was 68.1±9.6y (range: 32-81y). Mean follow-up time was 101.5±27.3mo (range: 60-144mo). Viscocanalostomy was performed in 8 eyes (25.8%) and phacoviscocanalostomy was performed in 23 eyes (74.2%). The mean preoperative IOP was 23.1±7.6 mm Hg with 2.1±1.0 medications, while mean IOP was 16.8±3.8 mm Hg with 0.9±1.1 medication at the last follow-up visit. Both the IOP decrease and the reduction in the antiglaucomatous medication were statistically significant (P<0.001 and P<0.001). No case required further glaucoma surgery. Overall success and complete success were found as 87.1% and 51.6%, respectively. Complete success rate was statistically higher in phacoviscocanalostomy group compared with the viscocanalostomy group (P=0.031), however there was no significant difference in overall success rate between two groups (P=0.072).CONCLUSIONBoth viscocanalostomy and phacoviscocanalostomy provide good IOP reduction in the long-term period.

AIM: To investigate the effects of novel hydrophilic chemotherapeuticdrugs on growth and apoptosis in human A549lung, SKVO3ovary andMCF7breast carcinoma cell lines. MATERIALS＆METHODS: Three new drugs: CQMU-0522,CQMU-0517and CQMU-0519were utilized on A549lung, SKVO3ovarian and MCF7breast human cancer cell lines, where cell growth wasassessed using cell culture kit-8and flow cytometry *** pathways for CQMU-0519were unveiled by annexin-V FITC,apoptosis DNA ladder, caspases-3,6,8and9;meanwhile, regulation ofBcl-2family members were analyzed by western blot analysis andATP-Tumor Chemosensitivity Assay was used on a fresh lungadenocarcinoma tissue to highlight the concerned drug in chemotherapy. RESULTS: CQMU-0522, CQMU-0517and CQMU-0519all suppressedcell growth in the three particular human cancer cell lines where cell cyclearrest was more evident in G2/M phase in the taxanes;while,CQMU-0522caused cell cycle arrest in G0/G1phase. Besides, in bothhuman lung and ovarian cell lines treated with CQMU-0519, apoptotic levels were higher according to various tests performed anddownregulation of Bcl-2and Bcl-xL genes with increased expressions ofBad and Bax genes favored a more intrinsic pathway for ***, it was found that MCF7cells though also manifesting highlevels of apoptosis preferred an extrinsic pathway instead of an intrinsicone. Since, lung adenocarcinoma cell line responded better to theCQMU-0519in terms of apoptosis, we decided to check for itschemosensitivity which is important for the pathologist to guide theclinician directing chemotherapy;where response rate for growthinhibition was better between a certain range of test drug ***, showing that the new docetaxel, CQMU-0519may have someprospective in the future in clinical trials. CONCLUSION: All the three new hydrophilic chemotherapeutic drugsanalogues inhibit cell growth and CQMU-0519enhances intrinsicapoptotic pathway in lung and ovarian carcinomas
